Saethre-Chotzen Syndrome
Saethre-Chotzen syndrome Authors: Professor L. Clauser1 and Doctor M. Galié Creation Date: June 2002 Update: July 2004 Scientific Editor: Professor Raoul CM. Hennekam 1Department of craniomaxillofacial surgery, St. Anna Hospital and University, Corso Giovecca, 203, 44100 Ferrara, Italy. [email protected] Abstract Keywords Disease name and synonyms Excluded diseases Definition Prevalence Management including treatment Etiology Diagnostic methods Genetic counseling Antenatal diagnosis Unresolved questions References Abstract Saethre-Chotzen Syndrome (SCS) is an inherited craniosynostotic condition, with both premature fusion of cranial sutures (craniostenosis) and limb abnormalities. The most common clinical features, present in more than a third of patients, consist of coronal synostosis, brachycephaly, low frontal hairline, facial asymmetry, hypertelorism, broad halluces, and clinodactyly. The estimated birth incidence is 1/25,000 to 1/50,000 but because the phenotype can be very mild, the entity is likely to be underdiagnosed. SCS is inherited as an autosomal dominant trait with a high penetrance and variable expression. The TWIST gene located at chromosome 7p21-p22, is responsible for SCS and encodes a transcription factor regulating head mesenchyme cell development during cranial tube formation. Some patients with an overlapping SCS phenotype have mutations in the FGFR3 (fibroblast growth factor receptor 3) gene; especially the Pro250Arg mutation in FGFR3 (Muenke syndrome) can resemble SCS to a great extent.

MEDICAL GENETICS RESIDENCY PROGRAM Department of Pediatrics
MEDICAL GENETICS RESIDENCY PROGRAM Department of Pediatrics University of Michigan Health Systems (734) 763-6767 1500 E. Medical Center Drive (734) 763-6561 (fax) D5240 MPB Ann Arbor, MI 48109-5718 Biochemical Genetics Goals and Objectives Director: Drs. Ayesha Ahmad and Shane C. Quinonez The goals and objectives of the Biochemical Genetics Clinic rotation in the Medical Genetics Residency Program are to provide the resident with exposure to all aspects of care of metabolic disease and counseling in accordance with the Residency Review Committee for Medical Genetics expectations and to fulfill criteria for board eligibility by the American Board of Medical Genetics. Patient Care The resident will become familiar with the evaluation, diagnosis and management of urea cycle disorders, organic acidemias, disorders of carbohydrate and lipid metabolism and numerous other inborn errors of metabolism (IEMs). Residents will gain exposure in performing and expertise in interpreting biochemical analyses relevant to the diagnosis and management of human genetic diseases. By the end of the rotation the resident should be able to identify signs and symptoms of IEMs, formulate a differential diagnosis, order appropriate tests and recognize normal variants and complex patterns of metabolites. Residents will be able to manage acute metabolic crises and provide chronic management of patients with an IEM. Residents should be able to interpret NBS results, collaborate with the primary provider to act upon results in a timely manner, develop a differential diagnosis and order appropriate confirmatory testing and communicate results to families. Medical Knowledge Through coursework and didactic sessions with attending physicians, residents will become familiar with fundamental concepts, molecular biology and biochemistry relevant to IEMs. -
Cherubism As a Systemic Skeletal Disease
Morice et al. BMC Musculoskeletal Disorders (2020) 21:564 https://doi.org/10.1186/s12891-020-03580-z CASE REPORT Open Access Cherubism as a systemic skeletal disease: evidence from an aggressive case Anne Morice1,2,3,4*, Aline Joly3,4, Manon Ricquebourg5,6, Gérard Maruani2,7,8, Emmanuel Durand9, Louise Galmiche2,10, Jeanne Amiel2,11, Yoann Vial12,13, Hélène Cavé12,13, Kahina Belhous14, Marie Piketty15, Martine Cohen-Solal6, Ariane Berdal1,16, Corinne Collet5,6, Arnaud Picard1,2,3,4, Amelie E. Coudert1,6,16† and Natacha Kadlub1,2,3,4† Abstract Background: Cherubism is a rare autosomal dominant genetic condition caused by mutations in the SH3BP2 gene. This disease is characterized by osteolysis of the jaws, with the bone replaced by soft tissue rich in fibroblasts and multinuclear giant cells. SH3BP2 is a ubiquitous adaptor protein yet the consequences of SH3BP2 mutation have so far been described as impacting only face. Cherubism mouse models have been generated and unlike human patients, the knock-in mice exhibit systemic bone loss together with a systemic inflammation. Case presentation: In light of these observations, we decided to search for a systemic cherubism phenotype in a 6-year-old girl with an aggressive cherubism. We report here the first case of cherubism with systemic manifestations. Bone densitometry showed low overall bone density (total body Z-score = − 4.6 SD). Several markers of bone remodelling (CTx,BALP,P1NP)aswellasinflammation(TNFα and IL-1) were elevated. A causative second-site mutation in other genes known to influence bone density was ruled out by sequencing a panel of such genes. -
SKELETAL DYSPLASIA Dr Vasu Pai
